The significance of this is Elon Musk, who is the self-driving Uber of dot.com billionaires and is the hero of our times.

Well, I knew Steve Jobs well enough, and have met a few civilian astronauts and a bunch of other rich people. None of the others seem to have done so much for the long-term future of the human race as Musk has in leading the path to more affordable spaceflight.

Well, it beats making them into the world's most complicated airplanes as with the space shuttle. SpaceX has proven that they can do vertical landings of the first stage intact onto both land and a seagoing barge; after a trip out of the atmosphere and to about 1/5 of orbital velocity but not into orbit. They plan to do a parachute-less vertical landing of the Dragon capsule after a heat-shield re-entry. That turns out to be far less expensive and complicated than a space plane. It does turn out we need a lifting body for much larger vehicles. It still doesn't have to be a plane, though.

We don't need wings.

I think scientists can make some larger statements on the impacts. No one can tell you what exactly it would be like at any particular location, But what you're doing is exaggerating the amount of uncertainty, and then trying to defend warming trends by invoking even less certain predictions. It's hard not to see how you aren't just being a contrarian simply because you don't like the answers science can provide.

When rain belts shift northward in North America, arid conditions will begin to become the norm in large parts of the American Midwest, and that will mean American food security will become, at some point over the next century so, one of the most serious issues the US has ever had to face. And this isn't a matter if whether it will happen or not, the debate is over WHEN it will happen.

Pumping vast amounts of formerly sequestered CO2 into the atmosphere is just plain bad. We should be moving at all speed to alternative energy sources, and either leaving the oil and coal in the ground, or finding some other use for it that doesn't involve releasing CO2 into the atmosphere.
